Tago adds that a star of magnitude 11.8, which did not show variability in his earlier images and which he identifies as GSC 3656-1328, is located very close to the new object's position of:

R.A. = 00h 09m 21.81s, Decl. = +54o 39' 43.8" (2000.0)

According to Green, apparently the GSC star is the same as listed in the USNO-A2 catalogue as 1425.00229853, having position end figures 22.00s, 44.0" and blue and red magnitudes 11.9 and 11.3, respectively.

A search at AAVSO of SIMBAD, the GCVS+NameLists, and VSX showed nothing variable close to the position of the new object.

Visual, PEP, and CCD coverage is requested; photometric observers should use a V filter if possible.

The position of the object lies within the field of the 'a' scale AAVSO chart for R Cas. The comparison star magnitudes on this chart go to 7.5, so they may be used while the object is so bright. The chart is at:
